At least four people have been killed in a new Taliban attack in Afghanistan’s capital, Kabul.

Taliban militants, backed by a suicide bomber, attacked a United Nations compound Friday evening and set off several explosions. In the ensuing gunbattle with security forces, at least one policeman was killed. Kabul’s police chief, General Mohammad Ayub Salangi, told VOA three of the attackers also were killed. At least 10 other people were wounded.

The blasts shook a busy area of Kabul, sending a plume of smoke over the city and causing chaos.

The general said the violence began when militants attacked a house next to the U.N. mission in Afghanistan. The Taliban said the target was a compound used by the U.S. Central Intelligence Agency.

This was the second major attack in Kabul in a little more than a week. On May 16, a suicide car bombing killed 15 people, including six Americans and nine Afghan civilians. Two of the Americans were soldiers.
